Recently, CERN (the European Organization of Nuclear Research) announced the discovery of a Higgs boson-like particle with a mass of 125 GeV. This discovery was made in the two photon and four lepton final states. The Higgs boson is a physical manifestation of the Higgs mechanism (spontaneous symmetry breaking) and was the only particle that had not been observed in the Standard Model. In this talk, I’ll discuss the Higgs boson in the Standard model and its possible discovery from the perspective of the experimentalists, with a focus on Duke’s role in the ATLAS experiment, one of the two experiments reported this discovery. Although the Standard Model has been highly successful in interpreting a wide range of data, it is considered incomplete as it does not include the gravity and dark matter. I’ll also present the status of experiments confirming if the new particle is the Higgs boson and the search beyond the Standard Model.
Coffee and cookies before the presentation at 3:15 pm, and refreshments after the presentation will both be served in Room 128.
